Reproductive biotechnologies such as in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT) enable improved reproductive efficiency of animals. However, the birth rate of in vitro-derived embryos still lags behind that of their in vivo counterparts. Thus, it is critical to develop an accurate evaluation and prediction system of embryo… (More)

We report three HIV-negative patients with spontaneous pneumothorax as clinical manifestation of active tuberculosis acute chest pain and dyspnea was the cause of admission. Chest roentgen grams showed lung collapse and parenchymal cavitation in two of therm and hydropneumothorax in the other. Outcome was favorable with antituberculous drug therapy and… (More)

The outcome of assisted reproductive technologies (ARTs) depends mostly on the quality of input material (oocytes and sperm) used in these procedures. The number of transferable embryos produced in these programs depends on both provision of high quality mature oocytes and adequate numbers of good quality spermatozoa capable of supporting embryo development… (More)
